.That I, PERLEY LAFLIN, of Warren,

Letters Patent No. 97,525, dated December 7, 1869.

IMPROVEMENT TN ATTACHING- CALKS TO HORSESHOES.

The Schedule referred to in these Ltt county of Worcester, and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Horseshoes; andI do hereby declare that. the following is a full, clear, and exact description of the same, reference being bad to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a bottom view of my improved horseshoe;

Figure 2 represents a top view; and

Figure 3 represents a section on line A B, fig. 2.

To enablet-hose skilled in the art to which my invention'belongs, to make and use the same, I will proreed to describe it more in detail .The nature of my invel'itionconsists First, in the combination, with the shoe, of hinged cross-braces, for supporting tbe'calks, substantially as hereafter explained;

- Second, in the combination, with the cross-braces for supporting the ealks, of the clan'iping-lugs, as hereafter described;

Third, in the combination, with 'the cross-braces of a conical clamping-nut, as hereafter described;

Fourth, in the combination, with the cross-supporti'ngbraces, of a hinged bolt-arm, substantially as here-- after described; and

Fifth, in the combination, with the hinged crosssupporting braces, of a conical clamping-nut and bolts'upport, as hereafter described.

In the drawings- A represents the .shoe, which may be made in the ordinary manner of making smooth shoes.

Combined with the shoe A are two cross-call; supporting braces, BB.

These braces are hinged together by aeentre-bolt or rivet, O, and are provided at their ends by ealks, a, which calks project from the lower sides of the crossbraces, leaving the upper sides smooth, which fit against the under side of the in the drawings.

, Projecting from the upper sides of the cross-braces B B are clamping-li1gs,b b and e c, which fitagainst the inner edge of the shoe, and are pressed against the same by the conical clamping-nut 1), which is fitted to screw upon the bolt E, in the end of the hinged arm F, which, in turn, is secured by a hinged jointv to the upper side of the cross-brace B, by means of the rivet or journal-piece O, which holds the cross-braces B B together, as indicated in the drawings.

The ends of cross-brace B are bent up slightly, so as to obtain a heating under the face of the shoe, the same as the ends of the cross-brace 1S.

shoe, as fullyindicated shoe, substantially as shown and setforth.

bolt support, substantially era Patent and making part of the sa ine .theconical clamping-nut'an even bearing-near its base on both sides, as indicated'in fig. 3.

To secure the braces B B, to which the calks are attached to the shoe, the horses foot is raised, and the clam'pingdugs Ii b and c c are slipped inside of the shoe, as shown in fig. 2, after which the conical clamping-nut G is turned on to bolt E, thereby forcing or spreading the ends of the cross-braces away from each other, and pressing the lugs b b and c 0 against the inner-edge of the shoe with great force. Q

I prefer to. make the lugs with an outward inclina tion or bevel, thusinsuring a more secure and firm hold upon the shoe.

From the foregoing description it will be seen that by my invention, the calks can he removed from and attached to the shoe of a horse in a ,very convenient and easy manner.

Then, again, the cross-braces prevent balling,

'while at the same time the strain upon the sh'oe is such as to keep the heel part from contracting about the frog of the foot, ,thns insuring an easy fit of the shoe.

By having the bolt E supported by a hinged arm, it

adjusts itself readily when'the conical nut D is turned up, thereby insuring a uniform hearing at each side of the nut D against the braces.

Haiin described my improved horseshoe,

What? claim therein as new, and of my'inventiim, and desire to secure by Letters Patent, is'

1. The combinatiomwith the shoe, ot' the hinged cross-braces which carry the calks, and means, substantially such as herein described, for spreading this ends of said braces, or projections on the same, against the 2. The combination, with the cross-supporting pieces B B, oi'a hinged bolt-arm, F, substantially as set forth. I

3. The combination,

with the cross-supporting braces B B, of a conical clamping-nut and hingedas and for the purposes set forth.
